Surround Sound from single speaker unit

From Slashdot news: "A one-speaker home theater system that is able to deliver surround sound has been unveiled by Nirotek America (Torrance, CA). The single speaker unit actually contains five individual speakers packed horizontally into a single case. The surround sound effect is achieved by playing some sophisticated psychoacoustic trickery on the human brain.

Realistic surround sound from movies and stereo CDs can be obtained as long as listeners are at least six feet away from the speaker unit and the unit stands near the front edge of whatever surface it is placed on. The unit is priced at around $799 and USA Today has a review."
